The literature from inception to 2020 on the prevalence of epilepsy in autistic individuals was systematically reviewed and further explored by subgroup analyses and meta-regression models. This systematic review is registered with PROSPERO (CRD42020179725). A total of 66 studies from 53 articles were included. The updated pooled prevalence of…

Mukherjee, Sharmila B.; Neelam; Kapoor, Seema; Sharma, Suvasini – Journal of Autism and Developmental Disorders, 2021
The Autism Dysmorphology Measure is designed for non-expert clinicians. It uses an algorithm to assess 12 body regions and categorizes Autism on the number of dysmorphic regions identified; Essential ([less than or equal to] 3), Equivocal (4-5) or Complex ([greater than or equal to] 6). We evaluated 200 Indian children with Autism (mean age…

Pillay, Sarosha; Duncan, Madeleine; de Vries, Petrus J. – Autism: The International Journal of Research and Practice, 2021
The prevalence of autism spectrum disorder in South Africa is unknown and, to date, very little research has been performed within school systems that could inform the rates, distribution and profile of needs of children with autism spectrum disorder in education. We performed a comprehensive database search of all children with autism spectrum…

Atladóttir, H. Ó.; Schendel, D. E.; Parner, E. T.; Henriksen, T. B. – Journal of Autism and Developmental Disorders, 2015
The aim of this study was to describe the profile of specific neonatal morbidities in children later diagnosed with autism spectrum disorder (ASD), and to compare this profile with the profile of children with hyperkinetic disorder, cerebral palsy, epilepsy or intellectual disability. This is a Danish population based cohort study, including all…

Jokiranta, Elina; Sourander, Andre; Suominen, Auli; Timonen-Soivio, Laura; Brown, Alan S.; Sillanpää, Matti – Journal of Autism and Developmental Disorders, 2014
The present population-based study examines associations between epilepsy and autism spectrum disorders (ASD). The cohort includes register data of 4,705 children born between 1987 and 2005 and diagnosed as cases of childhood autism, Asperger's syndrome or pervasive developmental disorders--not otherwise specified. Each case was matched to four…

We compared the prevalence and types of fractures in a clinical sample of 118 individuals diagnosed as children with infantile autism (IA) with 336 matched controls from the general population. All participants were screened through the nationwide Danish National Hospital Register. The average observation time was 30.3 years (range 27.3-30.4…

Wong, Virginia C. N.; Fung, Cecilia K. Y.; Wong, Polly T. Y. – Journal of Autism and Developmental Disorders, 2014
Data from 1,261 Chinese Autistic Spectrum Disorder (ASD) patients were evaluated and categorized into dysmorphic (10.79%) and non-dysmorphic groups (89.21%) upon physical examination by the presence of dysmorphic features. Abnormal MRI/CT result, IQ scores and epilepsy were significantly associated with the dysmorphic group of ASD children.…

Chapple, Christine; Kinsella, William – Educational Psychology in Practice, 2019
West Syndrome is a severe, early-onset epilepsy syndrome, with significant implications for subsequent neurological and cognitive development. While most children with a prior diagnosis of West Syndrome initially follow a normal developmental trajectory, there is evidence of subsequent emergence of clusters of difficulties, including autism…

Norrelgen, Fritjof; Fernell, Elisabeth; Eriksson, Mats; Hedvall, Asa; Persson, Clara; Sjölin, Maria; Gillberg, Christopher; Kjellmer, Liselotte – Autism: The International Journal of Research and Practice, 2015
There is uncertainty about the proportion of children with autism spectrum disorders who do not develop phrase speech during the preschool years. The main purpose of this study was to examine this ratio in a population-based community sample of children. The cohort consisted of 165 children (141 boys, 24 girls) with autism spectrum disorders aged…

Saemundsen, Evald; Juliusson, H.; Hjaltested, S.; Gunnarsdottir, T.; Halldorsdottir, T.; Hreidarsson, S.; Magnusson, P. – Journal of Intellectual Disability Research, 2010
Background: Research on the prevalence of autism in Iceland has indicated that one possible explanation of fewer autism cases in older age groups was due to an underestimation of autism in individuals with intellectual disabilities (IDs). The present study systematically searched for autism cases in the adult population of individuals with severe…

Epilepsy and Mental Retardation limited to Females (EFMR) which links to Xq22 has been reported in only one family. We aimed to determine if there was a distinctive phenotype that would enhance recognition of this disorder. We ascertained four unrelated families (two Australian, two Israeli) where seizures in females were transmitted through…
